What’s the most important Ground Reaction Force ? Dr Greg Rose @MyTPI 🎥 2025 S2M Summit
Dr. Greg Rose from the Titleist Performance Institute (TPI) presents at the Smart2Move Summit to break down Ground Reaction Forces in the golf swing. He explains how horizontal force, torque, and vertical force interact during the transition and downswing to maximize power and timing. Golfers and instructors will learn how proper ground interaction directly drives rotational speed and impact efficiency.
Ground Reaction Forces (GRF) are broken into three distinct components: horizontal (lateral), torque (rotational), and vertical forces.
Efficient transition requires generating horizontal force toward the lead target side early in the downswing.
Vertical force peaks just prior to impact to convert ground reaction into maximum clubhead speed.
Understanding individual force dynamics helps identify power leaks in a golfer's swing pivot.
